APPARATUS FOR PHOTOGRAPHING AND EXHIBITING KINEMATOGRAPHIC PICTURES.

SPECIFICATION forming part of Letters Patent No. 708,148, datedSeptember 2, 1902.

Serial No. 24,630. (No model.)

To all whom it may concern:

Be it known that I, LEONARD ULRICH KAMM, a subject of the Queen of GreatBritain residing at London, England, have invented new and usefulImprovements in Apparatus for Photographing and ExhibitingKinematographic Pictures, (for which I have applied for a patent inGreat Britain, No. 311, dated January 5, 1900,) of which the followingis a specification.

This invention relates to apparatus for photographing and exhibitingkinematographic pictures of the kind in which the pictures are arrangedin a spiral series on a transparent ring or disk; and it comprises theimprovements hereinafter described.

In the annexed drawings, Figure 1. is a rear view of the apparatusprovided with my improvements, the back being removed to show theinterior mechanism. Fig. 2 is ahorizontal section of the apparatus. Fig.3 is a sectional elevation of the left-hand portion of the apparatuslooking from the back. Fig. 4 is a view of aportion of the frontpart ofthe apparatus. Fig.5isasection onthelinexccinFige. Fig.6 isaviewofaportion oftheleft-handsideshown in Fig. 3 and showing some ofthe driving mechanism. Fig. 7 is a sectional elevation drawn to a largerscale than Figs. 1 to 6, showing how the rotating shutter can be readilyconnected to and disconnected from its Fig. 8 is a sectional side viewof the same, the section being on the line y y in Fig. 7. Fig. 9 is anedge view of the shutter detached. Fig. 10 is a rear elevation drawn tothe same scale as Figs. 1 to 6, showing means for clamping thepicture-plate in position when in the form of a disk; and Fig. 11 is asectional side elevation of the same.

Ct is the case of the apparatus, having the sliding back ct, and b is aslide carrying the sensitized or picture plate 0 through the medium of aclamping-plate c, a shaft (Z, and toothed ring 6, supported upon rollersc and operated intermittently by a spiral cain j" from a handlef andgear-Wheels f f the plate 0 being notched to engage a pin e on the ring6.

gis a pinion carried on the shaft (Z and engaging a rack-bar it, so thatwhen rotated it is caused to move the slide 19, the rack-bar beingpivoted at one end, so that it can be moved against the pressure of aspring to disengage it from the pinion g when it is required to move thepinion back to its initial position. The said spring serves to keep therack-bar and pinion in gear.

dis a lens, andj 7c are openings in the front and back of the case (L,respectively, and in line with the said lens, which openings can beclosed by plugs or caps Z.

m is a shutter on the shaft in, designed to be rotated between the lenst' and the opening it in the back ct of the case Ct by gearing from thewheel f All of the foregoing parts are of known construction.

The improvements according to my invention are as follows:

I arrange the slide Z), which carries the sensitized orpicture plate 0,to slide horizontally within the case a, and in order that the width ofthe apparatus shall not be increased in consequence I arrange the saidslide to slide through an opening a in one side of the casetelescopewise, as shown clearly in Fig. 2, the said slide being formedwith end and rear walls 1) b respectively, so as to inclose the plate 0at this part and prevent it being exposed through the opening oF, thewall Z) being detachable, so that the plate 0 can be removed and anotherplaced in position within the ring 6. The wall I) when in position onthe slide b is prevented moving sidewise by recesses on it engagingprojections b on the said slide. It is also prevented from movingbackward when the back a is in position by a strip 1'), formed upon it.

For fixing the sensitized or picture plate 0 to the shaft d on the slideZ) I arrange a disk '22, fixed on the said shaft, against which disk thesensitized or picture plate 0 is clamped by the clamping-disk c. Thisclamping is conveniently effected when the said plate is in the form ofa ring, as in Figs. 1, 2, and 3, by means of a nntn, loose on theclamping-disk and engaging a screw-thread d" on the said shaft, whichshaft passes through the opening in the sensitized or picture plate 0,and in order to prevent any slip between the plate 0 and the two disksthe latter are conveniently faced with india-rubber or the like n Whenusing a plate 0 in the form of a disk, as shown in Figs. 10 and 11, andnot of a ring,

loo

I dispense with the portion of the shaft 61 which was described aspassing through the ring form of plate and I provide a bar 0, whichextends diametrically across the said disk plate and. carries theclamping-disk c on a pivot 0', one end of the said bar being hinged tothe slide 1) through the medium of a bracket 0 while the other end isattached to the said slide by a suitable fastening, such as aspring-catch, for instance. The end of the bar 0 is convenientlyprovided with a spring portion 0 engaging beneath a pin or projection 0*on abracket 0 on the slide 17. In practice I prefer to arrange the bar 0diagonally on the slide 1), it being the only position in which it canbe arranged without materially interfering with the mechanism ornecessitating an increase in the size of the case a.

The spiral camffor intermittently rotating the ring e, carrying theplate 0, I arrange on a vertical shaftp in bearings 19 on the slide b,operated by bevel-wheels q g from a horizontal shaft 4, also in bearings0"]1 on the slide Z) and case a, respectively, and connected to thegear-wheelf and consequently to' the driving-handle, the said horizontalshaft 1" being formed in parts designed to telescope together, so thatthe driving connection is maintained between the said partsnotwithstanding the movement of the slide b. One part of the saidtelescopic shaft can conveniently be formed with a fork r engaging holesin a disk on the other part. In practice I prefer to utilize thebevel-wheel q for this disk.

In order that different forms of shutter (according to whether picturesare being taken or exhibited) may be readily attached or detaohed, thesaid shutters, as shown in Figs. 1, 7, 8, and 9, are each convenientlyprovided with pins 8 s, engaging holes 8' s in a disk 8 on theshutter-shaft m, a cam-plate t on the said shaft being designed whenrotated to engage with notches t in the pins (when the latter are placedwithin the said holes) and hold the shutter in position, as indicated inthe said'figurcs.

When exhibiting pictures, it sometimes happens that the center of thespiral series of pictures does not quite coincide with the center of thelens t'. In order that they may be made to coincide, I provide foradjusting the picture-plate c. This may conveniently be efiected bypivoting the rack-bar h, hereinbefore referred to, on an adjustablelever u, fulcrumed to the case a at a, and the outer end of which can beclamped when adjusted by any suitable means, such as a bolt 1; and nut42, engaging a slot 0 in a plate 1: on the case a. By loosening the nut11 on the bolt 4) and moving the lever tt on its fulcrum to the rack-barit will be caused to move longitudinally, and consequently move also theshaft (1 and picture-plate c.

In order that the lens 2' may be easily and simply adjusted forfocusing, I provide the tube or cell to, carrying the lens, with a pinto,

engaging a spiral slot to in a supporting-tube 10 so that by turning thelens on its axis by means of the pin to the lens will be caused to movelongitudinally in the said supportingtube. The lens t' in thesupporting-tube 103 is carried upon a partition 2, secured to the case,but which is detachable therefrom, so that the plate 0 can be removed,it being placed in position behind pins and strips 2* on the case andsecured by pivoted plates .2, engaging behind pins a 2 Fig. 3, is aspring-arm provided with an end a, designed to engage in the recessbetween two adjacent teeth of the ring c in order to hold thepicture-plate c rigidly in the interval between each movement by'thecamf.

1) represents pins acted upon by springs I) and projecting through oneside of the case a, so that when the pinion g has traveled to the outerend of the rack h and become disengaged from the teeth thereof the strip6 on the slide Z) will impinge against the said pins and be pressedback, so as to keep the pinion in contact with the last tooth of therack, so that if the handle f be turned backward the pinion 9 will becaused to again engage the rack h.

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, is
